Abstract: A method and apparatus for zig-zag folding in which stack lean can be corrected by angularly shifting one gripper-tucker member relative to the other where the gripper anvil tip and the gripper element tip are each a constant distance from the tucker tip during entry of the tucker into the gripper.

Abstract: An embossing roll has an embossing region that has a plurality of embossing elements. Each of the embossing elements projects outward from a surface of the embossing roll a distance of about 0.2 mm to about 2.0 mm. The plurality of embossing elements are arranged in the embossing region in a pattern. The plurality of embossing elements has at least a first set of embossing elements and a second set of embossing elements. The first set of embossing elements has a first shape and the second set of embossing elements has a second shape that is different from the first shape.

Abstract: A method includes a bag forming process with a bag wicketing machine having a sideweld seal head that receives plies of web material, conveys the plies through the sideweld seal head, seals the plies together, cuts the plies to form a bag blank, and moves the bag blank onto an exit conveyor. Pressurized air from nozzles of a pneumatic blow down bar is directed at the bag blank. With an energized laser operatively mounted on the pneumatic blow down bar, the position of the pneumatic blow down bar relative to the bag blank and the exit of the sideweld seal head is adjusted so that a beam emanating from the laser is positioned against the bag blank at a desired location where pressurized air from the nozzles of the pneumatic blow down bar is directed against the bag blank and forces the bag blank into engagement with the conveyor.

Abstract: An apparatus forms stacks of interfolded sheets. First and second folding rolls receive the plurality of sheets, move the plurality of sheets through the nip, and fold the plurality of sheets into a stack of interfolded sheets downstream of the nip. A packing finger is associated with each folding roll, and the respective packing fingers move between a retracted position and an extended position relative to the corresponding folding roll with alternate movement relative to each other between the retracted position and the extended position to engage the plurality of sheets and form the stack of interfolded sheets. A fluid delivery system delivers fluid to a sheet in the plurality of sheets at or after the folding rolls.

Abstract: A converting line has a unwind machine with a load station assembly and a vertical movement assembly. The load station assembly rotatably supports a roll as the web is unwound during a first portion of an unwind cycle. The vertical movement assembly rotatably supports the roll during movement between lowered and raised positions during a second portion of the unwind cycle. A lower brake assembly controls rotation of the roll in the load station assembly, and an upper brake assembly controls rotation of the roll with the roll in the vertical movement assembly. With the roll rotatably supported in the load station assembly, the converting line control generates signals for the lower brake assembly to control an unwind rotation rate of the roll. With the roll rotatably supported by the vertical movement assembly, the control generates signals for the upper brake assembly to control the unwind rotation rate.
